CAR-COUPLlNG.

SPECIFICATION forming part of Letters Patent No. 349,050, dated September 14, 1886. Application filed Juno 1886. Serial No. 206,184. (No model.)

To all whom it may concern.-

Be it known that I, JOHN T. Manson, of Laurel, Sussex county, State of Delaware, have invented a new and useful Improvement in Oar-Couplers, of which the following is a true and exact description, due reference being had to the drawings which accompany and form part of this application.

My invention consists in a novel method of constructing the locking device of a coupler; also in mounting the locking device upon the coupler instead of upon the platform of the car, as they are now constructed. By this means I am enabled to construct the coupling device so that the entire mechanism can be readily transferred from one car to another. I also increase the thickness of the metal at the point where the rivet connects the coupling-block with the jaws of the coupler. I also construct the draw-head with a rectangular orifice cut in it in place of the oval shape now in use, thus enabling me to make connection with any design of car.

In the drawings, Figure 1 represents a side elevation of coupler and locking mechanism; Fig. 2, a front elevation of same; Fig.3, aside section of same when coupling-block is open; Fig. 4, a front section with coupling-block open; Fig. 5, a side sectionwith coupling-block shut; Fig. 6, a front section with couplingblock removed; Fig. 7, aplau view with coupling-block shut; Fig. 8, aplan view with coupling-block open. Fig. 9 is a perspective view of my improved coupler and locking device, and Fig. 10 is a view of my improved bolt for locking the coupling-block.

Similar letters denote similar parts.

A designates the draw-head, having a rectangular orifice cut through its surface.

The use of a rectangular orifice in the d rawhead in place of a curved orifice enables me to adapt my improved coupler to any car. The draw-headis connected with the car in the usual manner. At the outer end, and cast with the draw-head, is the coupling-jaw B, and riveted or attached to one side of the jaw B is the coupling-block O, swiveling on pin 0, having tongue c, constructed in the usual manner, with the exception that the portion of the tongue of the coupling-block through which the rivet passes is made of greater thickness of the ordinary construct-ion, with the exception that the lower end is beveled off, as is shown at d, Fig. 10. This bolt projects through the jaw 13, as is shown, into the cavity 1) of the coupling-jaw. Near its upper end, and at the upper surface of the coupling-jaw, a collar sur rounds the bolt D and covers the hole by which it passes through the upper part of the coupling-jaw, thus preventing an accumulation of dust, grit, &c. This bolt is riveted at its upper end to one end of the lever E, which is fastened to the coupling-jaws by means of the block F. This lever E projects beyond the block, in which it is riveted at 0, so as to have free motion up and down. The lever is thus divided into two parts, e and o The arm 6 of the lever E may be constructed at right angles to the arm 6 of said lever E, so that the lever E may be operated from the level of the platform of the car to which the coupler is attached. This lever E is so constructed that the bolt D is normally in the position shown in Fig. 2, and when moved out of that position to the one shown in Fig. 4, unless so held, it will return to its former position.

The operation is as follows when it is desired to couple two cars together: The couplingblock strikes the tongue 0 ofthe coupling-block of the other car, and the tongue is forced against the beveled end of the boltD and passes, raising the bolt to the position shown in Fig. 4. \Vhenthe tongue has passed beyond the bolt D, the bolt, as has hereinbefore been explained, returns again to its former position, and the other surface of the bolt being straight the tongue is held fast in its position, and the coupling-blocks of thecars, fitting into each other, are held in a fixed position. \Vhen it is desired to separate the cars, the lever-arm e is operated, which lifts the bolt D, so as to allow the tongue 0 to return to its open position, and thus remove the connection between the coupling-blocks of the cars and allow the cars to become detached from each other.

In many cases it is desired to push one car against another without coupling, and to accomplish this I attach a pawl, G, to arm 0" of the lever E. This is constructed so as to nor-, mally remain in the position as shown in Fig. 2, which does not affect in any way the operation of the coupling mechanism, as hereinbefore shown; but when the pawl is turned to the position as shown in Fig. at it causes the bolt D to be shifted up, so that the tongue 0, when the cars come together, will have afrec movement backward and forward, the lowerend of the bolt being above the top of the tongue, and when the car which was pushed into the other is moved off from it the two couplingblocks will separate from each other without the necessity of operating the lever E.

Having now described myinvention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a cai'coupler, a draw-head having a rectangular orifice cut through it, substantially as and for the purpose specified.

2. In thelocking meehanismofa car-coupler, the locking-bolt D, the surface of said bolt being beveled from near the lower end to the foot of said lookingbolt.

3. In the locking mechanism of a ear-coupler, the combination of the locking-bolt D, the surface of said bolt being beveled from near the lower end of the foot of said l0cking-bolt, and tongue, said tongue being so constructed and arranged as to lift and pass beyond the said bolt 1), substantially as and for the purpose described.

4. In the locking mechanism ofa car-coupler, the combination of locking-bolt D and lever E, said lever E being attached to the coupler, substantially as and for the purpose specified.

5. In thelocking mechanism ol'a ear-coupler, the combination ofa locking-bolt, D, lever-arin a, and lever-arm c", said lever-arm 0 being at right angles to said lever-arm 0 substantially as and for the purpose specified.

6. In the locking device ola car-coupler, the pawl G, attached to the lever-ar1n c substantially as and for the purpose specified.

7. In theloeking mechanism of a car-coupler, the combination of locking-bolt I), levenarm c, lever-arm a, and block F, all constructed and acting substantially as and for the purpose specified.
